Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim 1, as best understood, is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Forsell (U.S. Publication No.2021/0393301 A1). Regarding claim 1, Forsell discloses a wirelessly operable implant system for providing controlled lengthening of a bone comprising: an intramedullary bone lengthening nail (300) attached to bone segments (Figure 11), wherein the intramedullary bone lengthening nail is configured to one of: distract the bone segments and compress the bone segments (see the embodiment of Figure 7a and 11) upon receiving a rotational motion in one of a clockwise direction and anticlockwise direction at an input member of a motion translation unit (via electrical motor 302, see para.0206), the motion translation unit is integrated in the intramedullary bone lengthening nail (see Figure 7a); an extramedullary implant (electrical motor 302) operatively connected to the intramedullary bone lengthening nail for providing the rotational motion in one of: the clockwise direction and the anticlockwise direction at the input member of the motion translation unit (para.0206), the extramedullary implant comprises: a receiver (external energy-transmission device 304) configured to receive at least one of: energy and one or more control signals wirelessly (para.0295); an implant control circuit (switch 323); an actuator configured to provide one or more actuations for providing the rotational motion to the input member (see actuator 305 in Figure 7a, see also para.0206) of the motion translation unit (302) whereby operating the intramedullary bone lengthening nail (para.0206); one or more actuation feedback sensors (325) configured to sense the provided one or more actuations (para.0314); acoustic transmitter configured to transmit one or more acoustic signals wirelessly (external energy-transmission device 304 also includes a wireless remote control having an external signal transmitter, see para.0290); and an extracorporeal wireless controller operatively connected to the extramedullary implant for transmitting at least one of the energy and one or more control signals, and receiving the one or more acoustic signals (para.0290), the extracorporeal wireless controller comprises: a transmitter (para.0290) configured for transmitting at least one of the energy and the one or more control signals wirelessly to the extramedullary implant; a control board (para.0295); and an acoustic receiver (para.0295) configured for receiving the acoustic signal as a feedback signal from the said extramedullary implant (para.0295), whereby providing the controlled lengthening of the bone. PNG media_image1.png 420 580 media_image1.png Greyscale Allowable Subject Matter Claims 2 and 3 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 4-8 are allowed, once the claim objections and rejections under 35 U.S.C. 112(b) discussed above have been resolved. Claim 2 in the instant application have not been rejected using prior art because no references, or reasonable combination thereof, could be found which disclose, or suggest, the claimed combination of limitations recited in independent claim 1 and dependent claim 2. In particular, none of the cited references teach or suggest wherein the extracorporeal wireless controller comprises: the transmitter configured to generate electromagnetic waves modulated in patterns corresponding to distinct control signals of the control signals, wherein the electromagnetic waves transfer the energy and the one or more control signals concurrently; and the receiver of the extramedullary implant configured to receive at least one of the energy and the one or more control signals, wherein the control circuit of the extramedullary implant is configured to interpret the control signals to execute one or more actions including one of lengthening actuation, compression actuation, transmitting identity, and transmitting actuation feedback, as required by claim 2. Claim 3 in the instant application have not been rejected using prior art because no references, or reasonable combination thereof, could be found which disclose, or suggest, the claimed combination of limitations recited in independent claim 1 and dependent claim 3. In particular, none of the cited references teach or suggest wherein the extramedullary implant is configured to perform a bidirectional exchange of wireless signals with the extracorporeal wireless controller, the extramedullary implant configured to transmit the one or more acoustic signals including identity details, actuation performed by the actuator, and status of the extramedullary implant, to the extracorporeal wireless controller, wherein the extracorporeal wireless controller upon receiving the acoustic signal from the extramedullary implant, configured to determine one or more course of actions, the one or more course of actions comprises one of transmitting at least one of the energy, and one or more control signals corresponding to lengthening of bone, compression of bone and query for identity of the extramedullary implant; and interrupting transmission of at least one of the energy and the one or more control signals, as required by claim 3. Claims 4-8 in the instant application have not been rejected using prior art because no references, or reasonable combination thereof, could be found which disclose, or suggest, the claimed combination of limitations recited in independent claim 4. In particular, none of the cited references teach or suggest an extramedullary implant operatively connected to the intramedullary bone lengthening nail for providing the rotational motion in one of the clockwise direction and the anticlockwise direction, at the input member of the motion translation unit, wherein the extramedullary implant configured to be operated magnetically, comprises a driven magnetic array coupled to a gearbox, wherein the gearbox operatively connected to a connecting shaft, the connecting shaft operatively connected to the input member of the motion translation unit; and an extracorporeal wireless controller operatively connected to the extramedullary implant for magnetically operating the extramedullary implant, the extracorporeal wireless controller configured to be placed on a skin extracorporeally covering the magnetically operated the extramedullary implant, as required by claim 4.
